Just finished TRE surgery on my GSR600 and the midrange is noticeably better. A power commander it aint, but considering it cost me all of 25cents I'm not going to complain, and anything that gets rid of shit emmission restrictions MUST be done!

My only issue thus far is that it has increased the fuel switching in 1st and 2nd. Take a tight corner and start to put the juice back on half way around and WACK. Theory thus far is the extra bottom end oomf from the TRE eccentuates the fuel switching issue the GSR's have. Will see how it goes, if its too much a pain in the arse, and the extra power is not big enough then I'll revert back to original and keep saving for the power commander.

So thats the REAL cheap bits done (O2 sensor eliminator and TRE). Next is the air filter, decat pipe and then cans....and maybe some renthals....some race knobs....
